GBLUP prediction correlation coefficient and bias within the MASPOT panel over a number of annotated markers. The markers were reduced from full annotated SNP data sets by iterative reduction to every other marker (every 10th for the final reduction) to avoid the introduction of positional bias. Each reduction was repeated up to four times for each iteration. Color by marker annotation (SNPtype). (A) Prediction correlation coefficient between observed and predicted phenotypic values. Boxplots of correlation coefficients determined for each marker count with connecting lines through the mean. (B) Bias of GEBVs estimated as the slope of the linear regression line between observed and predicted phenotypic values. Boxplots of biases determined for each marker count with connecting lines through the mean bias.
